HUADISK SSD

The HUADISK HYV1TBX4(GR) hits 7200 MB/s reads and lands in the 89th percentile for random performance, which is genuinely impressive for a $150 drive. But it's QLC with no DRAM, so sustained writes will crater once the cache fills. The 3-year warranty also contradicts the manufacturer's own site claiming 5 years, which doesn't inspire confidence.

Let's talk numbers. The 7200 MB/s sequential read and 6400 MB/s sequential write put this drive in the 82nd percentile for speed, which is solidly above average. For context, that's faster than most PCIe 4.0 drives we've catalogued, and it's approaching the ceiling of what the interface can do. The random IOPS are even more impressive: 720K read and 800K write, landing in the 89th percentile. That's one of the best random performance profiles we've seen in this category, which is unusual for a budget QLC drive.

But there is a catch with QLC without DRAM. Those peak numbers are almost certainly coming from the SLC cache, and once that fills up during a large file transfer, you'll see write speeds drop dramatically. The spec sheet doesn't tell you how big that cache is or what the post-cache write speed looks like. For everyday gaming and boot drive duty, you probably won't notice. For sustained video editing or massive file moves, you absolutely will.

Stacked against the Samsung 9100 PRO, this HUADISK actually matches or beats it on paper for random performance, which is wild for a drive at this price. But Samsung brings DRAM, TLC NAND, and a brand reputation that means something when your data is on the line. The Crucial T710 and Western Digital SN7100 both offer similar PCIe 4.0 speeds with better endurance and actual customer support infrastructure. The Lexar NM1090 PRO is probably the closest competitor in terms of the value play, and it has a stronger track record. The Micron T710 is in a different league entirely for reliability. If you're buying this for a PS5, the console use case score of 57.9 out of 100 should give you pause, the console demands sustained performance that QLC drives struggle with.

At $150 USD for 1TB, this drive is priced to compete with budget options from established brands, but it's not the screaming deal you might expect from an unknown name. You're paying roughly the same per-gigabyte as some entry-level drives from Crucial or Western Digital, while getting better peak performance but worse brand trust. The value proposition really depends on whether those random IOPS numbers hold up in real-world use. If they do, this is a steal. If the QLC cache issues bite you, you'd have been better off spending the same money on a slower but more consistent TLC drive.

The HUADISK HYV1TBX4(GR) is a 1TB PCIe 4.0 drive claiming 7200 MB/s reads and 6400 MB/s writes, which puts it right up there with drives that cost a lot more. On paper, those numbers are genuinely impressive for a no-name brand. The random performance is the real surprise here, landing in the 89th percentile of our database, which means it handles scattered small-file workloads better than most drives we've tested.

But there's a catch, and it's a big one. This is a QLC drive with no DRAM cache. That combination usually means sustained write performance falls off a cliff once the SLC cache fills up. The 600 TBW endurance rating is decent for QLC, sitting in the 81st percentile, but you're still getting a drive from a brand most people have never heard of, backed by a 3-year warranty when the Q&A section suggests the manufacturer's own site claims 5 years for consumer drives. That inconsistency is worth noting.

If you're doing any kind of sustained write workload, video editing, large file transfers, database work, skip this drive. The QLC NAND without DRAM means write speeds will drop off a cliff once the SLC cache is exhausted, and the 33rd percentile feature score means you're not getting any extras to compensate. Console users should also look elsewhere, the 57.9 out of 100 console score is below average, and the portable use case score of 14.9 is one of the worst we've seen. If you need a drive you can trust with important data, the 5-review social proof and warranty inconsistency should send you running to Crucial or Samsung.

The HUADISK HYV1TBX4(GR) is a weird one. The peak performance numbers are genuinely competitive, with random IOPS in the 89th percentile and sequential speeds in the 82nd. But those numbers come with QLC NAND, no DRAM, a 3-year warranty that contradicts the manufacturer's own website, and a brand with almost zero track record. For a secondary game drive or a budget boot drive where you're not pushing sustained writes, it's worth considering. For anything where your data matters or you need consistent performance, spend the same money on a TLC drive from a brand you've actually heard of.
